A doctor is advising people to keep a glass of room temperature water beside their bed to help reduce the risk of heart attack in the morning. The practice, though simple, may counteract a dangerous spike in cardiovascular strain that occurs upon waking.
According to Spanish doctor Alberto Sanagustín, the period between 6am and 10am sees a high number of cardiovascular incidents due to a combination of hormonal changes. Upon waking, the body releases cortisol and adrenaline, stiffening arteries, while a substance called PAI-1 blocks the natural breakdown of blood clots. This creates what he describes as a 'perfect storm' for heart attacks.
Drinking water at room temperature immediately after waking helps hydrate the body and makes blood flow more freely. It also sends a signal to tighten blood vessels and raise blood pressure just enough to prevent dizziness, the doctor says. He characterises the advice as a 'zero-cost lifesaver' that prepares the body gradually for the day ahead.
Other health sources offer mixed views. WebMD suggests adding lemon to morning water for extra nutrients, while Healthline argues that overall hydration throughout the day is what matters, not timing. Dr Sanagustín also emphasises the importance of rising slowly, sitting up in bed for a few moments before standing, to avoid sudden strain on the system.
